Look up Anita Howe, Howe They Walk farm - she has youtubes, a website, and does clinics. She made a a YUGE difference in my own TWH who gets tense and pacey. Her videos are helpful in understanding the gaits and how variable they can be; meaning I have 4 TWH and all four feel very different in their gaits. Just as horse’s trots are not the same horse to horse, nor are the walking gears.
The big thing to know is that a RW tops out at what, maybe 8-10 MPH? And that head should be nodding straight up/down, no waggling L/R. If her head gets still and she’s flying along smoothly, she’s racking which is loads of fun but isn’t a RW, A strong RW feels powerful and 4 cornered, you hear each hoof distinctly…it’s addictive Racking feels like you’re on rails.
ok I did it, here’s Anita:

her stallion has more shake than I want in a trail horse, but that shows you how variable they are:

this boy I LOVE…that’s my style of horse, notice the loose reins, nose out, in balance and not on his forehand

I think this will give you ideas on speed and on rhythm. Have fun!
